From the manufacturer:
The FX series flow switch is the most reliable flow switch available. The thermal dispersion principle of operation features no moving parts and provides an extremely reliable and repeatable switch for the most demanding industrial applications. The sensor head employs two temperature sensors with a constant very low power heating source physically attached to one of the temperature sensors. The second temperature sensor is isolated from the heating source and provides compensation for changing process temperatures. As flow changes so does the temperature differential. This allows the device to be used as a flow/no flow sensor and to be used to switch at any velocity shown in the flow switch range chart. Extremely low flow rates can be detected with rangeability up to 300:1.
These devices are ideal for use in virtually all liquids, gases, and slurries. With no moving parts exposed to the process end users are provided an extremely reliable and repeatable instrument even in viscous or corrosive applications. The electronics are available with single or dual switch points. Temperature monitoring is also available with either a switch output or a linear 4-20 mA output. Relay outputs are standard and are offered with several different configurations and contact ratings. Remote mounting of the electronics is also available.

APPLICATIONS
Pump Protection:
The FX series flow switch can reliably shut down pumps on low or no flow
Bearing Lubrication:
Detects loss of lubricant flow
Seal Leakage:
Switch verifies positive seal flow or detects excessive leakage indicating maintenance requirement
Chemical Feed and Metering Pumps:
Indicates low or no flow of chemical additives to process fluids down to .02 feet/sec
Safety Shower and Eye Wash Station:
The FX series switch detects high flows from a safety shower and the low flows of an eye wash station. It can be wired to sound an alarm, turn on an emergency light, and/or send a signal to the control room for emergency help.
Analyzer/ Gas Chromatographs:
Confirms continuous sample flow to instruments
Control Rooms:
A flow switch can be used for monitoring of plant equipment such as pumps, valves, and fans, providing a contact closure when the process condition changes.
Purge Air:
Detects or verifies flow to meet plant safety requirements
Spray Nozzles:
A flow switch can reliably detect nozzle blockage in coating applications
Relief Valve/Rupture Disks:
The FX switch can provide automated detection of flow or leakage of safety relief valves or rupture disks
Chiller Lines:
Automatic shut down of chillers on low or no flow
Heater Burnout Prevention:
The FX series flow switch can initiate heater shutdown on loss of flow to prevent overheating of elements
Tank Car Loading:
The FX senses dry line or phase change from liquid to nitrogen gas flow
Drain Line Sensor:
Capable of detecting low flow in partially filled lines
Agitation Monitor:
Provides positive indication of agitation in tanks, vessels, or ponds
Flare Stack Monitor:
The FX series no moving parts thermal dispersion flow switch is ideal for monitoring dirty gases in flare stack applications
